It's no secret that some people play fast and loose with airport security rules, and the news cycle has picked up on some extremely interesting TSA discoveries over the years: A man hiding snakes in his pants? Check. A woman smuggling a chihuahua in her carry-on? Check. People casually packing a human skull and live eels? Check and check. And as it turns out, 2018 was not immune to the craziness. On Monday, TSA posted a video on YouTube titled "Top 10 Most Unusual Finds of 2018," which details the strange, weird, and downright dangerous items they discovered last year. (In case you were wondering, yes: snakes made another appearance in 2018.)

Here are some items that were discovered at the following airports:

Razor glove, Hartsfield–Jackson Atlanta International Airport (ATL)

Inert mortar round, Evansville Regional Airport (EVV)

Giant scissors, Nashville International Airport (BNA)

Tuxedo grenades, Newark Liberty International Airport (EWR)

Replica explosive device, Chicago O'Hare International Airport (ORD)

Concealed knife in baby carrier, LaGuardia Airport (LGA)

Snakes in computer hard drive, Miami International (MIA)

Saw blade glove, Denver International Airport (DEN)

Spear gun, William P. Hobby Airport (HOU)

Ice axe, Chicago O'Hare International Airport (ORD)

The TSA has some delightful commentary to go along with each item (our favorite: "One man's emotional support object is another man's inert mortar round"), so we recommend checking out the entire video for yourself. If you're unsure of what you can and cannot bring through airport security, you can check out TSA's website. But a general rule of thumb: If your vacation truly won't be complete without a giant sharp object, that's what checked baggage is for.
